I just wanted to link some tools that are cheaper to help people get started:
µCurrent – EEVblog - gerbers available and the banana plugs are available from Frankie on eBay he supplies a lot of quality stuff that is recommended from EEVBlog forum. I have several of his measurement cords and always good quality. www.franky.com redirects to 99centHobbies | eBay Stores
@mbrugman I am having some Ucurrent gold pcb’s made when they are done I will contact you and send you some in the mail your not far from me but I know your thinkering away on the glitch projects.

Oh wow - thank you very much!
Thanks for linking these. Especially the first one looks interesting to me.
The designs based off the EEVblog µcurrent aren’t particularly fast. Bandwidth in the order of low kilohertz. This doesn’t need to be a bad thing due to less noise, but it isn’t enough for some applications.
For example when you want to extract data from a power side channel or want to precisely time a glitching attack it might not be enough.

Oh, and since we are on the BusPirate forum:
Feature request:
The BusPirate has an integrated scope mode. Also an integrated voltage regulator with a shunt to measure current, wired via some opamp to the ADC. So it would be possible to show current draw from Vout on the screen in scope mode.
This could be helpful to debug some DUT, by looking at its power consumption.
Maybe a roll mode would be nice for this and some slower timebases.

wait…this is the bus pirate forum? ^— - I agree, would be interesting to see what could be done, was thinking that the blank plank would be useful here but not sure. But just like with a few other tools, on my own pcb test boards, I stripped out usb connectors to just two wires, soldered them into bannana plugs to measure the MCU consumption in the low mv/current.
